GNU libmicrohttpd 0.9.72

This release is mostly bugfix release, with greatly improved compatibility with various OSes/kernels, including FreeBSD, Windows, OpenBSD, NetBSD, Darwin (macOS), Solaris. Performance is improved, especially with stay-alive HTTP and HTTPS connections.

Notable changes since version 0.9.71:

• New function MHD_create_response_from_pipe().

• Fully rewritten code for buffering/pushing from kernel network buffers for compatibility with various OSes. Reduced number of additional sys-calls, network is better utilized, responses are delivered faster. Restored optimal sendfile() usage on FreeBSD.
• MHD now takes care about SIGPIPE handling by blocking it in internal threads and avoiding functions (like sendfile()) that could generate SIGPIPE when blocking of this signal is not possible.
• Fixed crash in PostProcessor.
• Fixed several resources leaks in corner cases.
• Improved thread sync, thread safety and fixed one use-after-free under special conditions during stopping of daemon.
• Updated HTTP status codes, header names and methods from the registries.
• Fixed functioning without listen socket and with internal threads.
• Fixed streaming of chunked responses for both HTTP and HTTPS.
• Various compatibility fixes.
